Genetic Map for Aging in Mice
Filed in archive Genomics, Proteomics and Bioinformatics by ruth on November 30, 2007
As an organismages, most tissues change their structure (for example, muscle tissues become weaker and have slow twitch rather than fast twitch fibers), and all tissues are subject to cellular damage that accumulates with age. Both changes in tissues and cellular damage lead to changes in gene expression, and thus probing which genes change expression in old age can lead to insights about the process of aging itself.
Previous studies have studied gene expression changes during aging in just one tissue. The new work stands out because it is much larger and more complete, including aging data for 16 different tissues and containing over 5.5 million expression measurements.
